Meaning

Politics is such a dirty game. Often it seems as if these politicians are more worried about re-election then taking solving the issues we entrusted them to fix (in this case the unemployment rates). Here Obama says things are going to change this time around (especially in terms of jobs for the millions of unemployed Americans, who are the core of this line) which is easy for him to say since he not running for re-election again.
